I've started to try and figure out the rock band unplugged chart format (.STR). Only lead I've figured out is 4 blocks of pure random Harmonix console shit appearing. This seems to be useless as I zeroed a massive chunk and it still worked
found the bytes that seem to point to the chart. these are the first different bytes out of the songs, replaced the "header" with one from the beta's panic attack chart and it produced some shit. easy worked, medium and hard crashed, expert got ingame but didnt load any tracks and softlocked. i changed the left column of bytes to all be the same and now all difficulties aside from easy all load the expert chart
now i gotta figure out how these left most bytes point to the chart. yet to figure out the other 2 columns, im thinking right most is the end but idk about the middle.
